Colorado has some of the most incredible hiking in the country. From the the deep Black Canyon of the Gunnison, to the highest point in Colorado on Mount Elbert, there is a lifetime of hiking to explore.

The amazing part about hiking in Colorado is that not all hikes need to take a full day. Many hikes include short drives from the Denver metro area, or from tourist towns in the mountains. Whether you’re looking for hikes to a waterfall, a secluded walk in the woods, or a full day adventure up a 14er, there are endless options for all levels of hiking experiences. There are 54 peaks over 14,000 feet in Colorado, and all of them have challenging hiking options!

There are different difficulties of hiking for all levels and interests. Being that is a an overview of the best hiking in Colorado, this article could go on for days. Be on the lookout for more articles in the future for the best 14er hikes and multi-day backpacking trips. This article will mainly focus on some of the best day hikes.

There are many different factors to consider while hiking in Colorado. Weather, accessibility, hike difficulty, length, and elevation gain are all factors to consider when choosing a hike in Colorado. Hiking weather in Colorado is incredibly variable and can change at any time. One can experience snow storms in June, warm weather in February, or even a sunny summer day interrupted by intense thunderstorms. It is important to always bring extra layers and a waterproof jacket while hiking in Colorado.

With thousands of hikes in Colorado, there is no way all of them can be featured in this article. Featured below will be some of the best hikes in Colorado for all different types of hikers that include some of the best views in the state.

Let’s start with some common questions about hiking in Colorado.

How much hiking does Colorado really have?

35% percent of land in Colorado is public land or a whopping 23 million acres. Much of this land has developed hiking trails, spanning 12 National Parks, 41 State Parks, and 58 mountains above 14,000 feet. Mountains above 14,000 feet are known as 14ers. Different public lands have different guidelines and restrictions, so it is important to be familiar with the area that you are hiking in.

Not all public lands are free to enter. Some Colorado State parks and all National Parks have fees to enter the park. Others also have parking fees. Generally speaking, if the hike is on National Forest land, there will not be any fees associated with accessing the hike.

A fantastic way to explore hiking trails on public land in Colorado is via the Colorado Trail Explorer App. This is available as a desktop version as well on Iphone and Android. This is a great way to have a visual look at all of the trails in the state. You’ll never know what you could find! This is a great resource released by the Colorado Department of Natural Resources and Colorado Parks and Wildlife. It covers more than 39,000 miles of trails on public land, as well as private land with public access. Cross-referencing that app with All-Trails, or the Outbound App can prove for some awesome adventures.

When to hike in Colorado?

One can hike all year round in Colorado. Although, winter lasts a long time in the high country. Generally speaking, the “high country” is referred to as the area at 9,000 feet and above. One can encounter snow on Colorado hiking trails all year round. The majority of the roads up to the high alpine backcountry do not open until June every season. While there is plenty of hiking all year round, hiking into the high alpine is best during July and August.

Spring can be a tough time to hike, depending on the conditions. For some parts of the state, it is starting to get warmer, and the flowers are blooming. For the more alpine regions, spring can either still be winter, or it can be very muddy. Generally speaking, areas above 9,000 feet in spring time are definitely still covered in snow. Snowshoes and micro-spikes can be used on higher elevation trails well into May. With any season, conditions can be variable. Be sure to check on trail conditions using All-Trails, or by contacting the proper park manager to inquire about trail conditions. There are also great groups on facebook that post trail conditions.

While summertime is the best time to venture into higher altitude hikes in the alpine, the summer also has its dangers. The intense heat of the summer makes the high altitude areas prime for late afternoon thunderstorms. When hiking above treeline, it is incredibly important to watch the weather and be off the summit before 2pm. Thunderstorms can be incredibly dangerous, and even fatal. Being on an exposed ridge top on a late summer day is one of the most dangerous places to be while hiking. This leaves one exposed to lightning strikes, which causes about 2 fatalities per year in Colorado. The summer can also bring snow and hail when you are least expecting it, be sure to be packed for all weather conditions!

Fall is one of the best times to hike in Colorado. In many parts of the state, fall colors highlight the woods. Popular fall hiking can be found in Rocky Mountain National Park (RMNP), and near the towns of Vail and Aspen. Fall can quickly turn to winter in some areas of the state. The first snowfall up high can occur as early as the first week of September! Some of the most amazing landscape shots from Colorado occur during fall colors and that first snowfall.

Winter brings solitude through deep snow in the woods. Heavy snowfall shuts down the majority of hiking in the alpine environment due to avalanche concerns as well as intense cold weather. If you are traveling in or under avalanche terrain, be sure to be educated on avalanche safety. You can learn more about avalanche forecasting and avalanche safety at the Colorado Avalanche Information Center. Avalanche terrain should be taken very seriously. Be sure to have the right education and the right gear.

What to bring hiking in Colorado?

There are many different items one should bring hiking while in Colorado. Regardless of the hike and weather conditions, you should always bring extra layers, extra food, and a first aid kit. The weather is very unpredictable in Colorado. Be sure to have checked the forecast multiple times, and do always bring extra layers as well as a rain jacket. Some hikes may recommend hiking poles, or even a helmet while scrambling on more technical hiking trails. Compared to the rest of the country, cell service in Colorado is not that great. Be prepared to not have cell service while you hike. It is a good idea to look into purchasing a mode of communication for emergencies such as a SPOT or a Garmin Inreach.

What to wear while hiking in Colorado?

While hiking in Colorado, it is advisable to wear hiking boots that give your feet and ankles good support. This will prevent injuries while hiking on rocky ground. While shorts may be more comfortable for lower elevation hikes in the heat, It is advisable to wear long pants, regardless of the outside temperature. Thin, long pants can be very breathable and will prevent injury from low lying branches scratching up against you on the trails. Pants will also be nice to have in case of a rogue thunderstorm. Quick rainstorms and thunderstorms are also not uncommon up in the high country. A small, packable rain jacket can be great to throw in your pack. While hiking in snow or mud, gaiters can be great to throw over your pants as well. This will prevent your legs from getting cold and dirty!

Will I get altitude sickness hiking in Colorado?

Even for someone that lives in Colorado, anyone can get altitude sickness when hiking up high, most commonly above 8,000 feet. As with any hiking day, it is especially important to drink lots of water and make sure you are eating enough. The easiest thing you can do to prevent altitude sickness is drink water and make sure you do not ascent too much in one day. For example, if you were flying in from sea level, it would be dangerous to try and hike a 14er the next morning. Your body needs to acclimate to the higher elevation. Altitude sickness is important to be aware of when hiking at higher elevations. Become educated on the topic, and be sure to keep an eye on those hiking with you. Here is an article about getting altitude sickness in Colorado.

Getting there

Many hikes in Colorado are accessible with a 2-wheel drive vehicle. Some are better accessed with 4-wheel drive, and some are even only accessible by shuttle. If you are flying into Colorado, Denver International Airport is the best option. From there you are only a few hours from incredible hiking destinations! As was mentioned above, some roads are closed for portions of the year, it is important to check on those closures. Most high alpine roads will open up in June each summer.

Where to hike in Colorado?

Here comes the big question! Where should I hike in Colorado? For the purpose of this article, we will divide the state into different regions and look at some of the best hikes in different parts of the state. Some areas of the state obviously have better hiking options than others, but this will be a great way to understand the lay of the land. These geographical regions are subjective, but will provide a good layout of hiking in the state. Here are the regions we will use.

Northern Front Range

This area will encompass Denver north to Fort Collins with hikes that are accessible from the eastern urban corridor. This has arguably the highest concentration of accessible hikes in the state due to the Boulder area as well as the Indian Peaks Wilderness, and Rocky Mountain National Park. If you are looking for a quick way to escape the city, this is a great region to hike in. Hikes here range from short walks in Boulder’s Chautauqua park to hiking Longs peak, a 14er.

Southern Front Range

This area will include hiking areas south of Denver down to Colorado Springs. Colorado Springs also has a great number of hikes close to town and is under the shadow of Pikes Peak, a 14er.

I-70 Corridor

This large area will include hiking near the popular ski resorts of Colorado. Hikes near towns such as Breckenridge, Vail, and Aspen will be included in this area. The hikes in this area are commonly at higher altitudes and will often start at 9,000 or 10,000 feet above sea level. Some of the best fall colors can be seen in this area. This also has a high concentration of popular 14er hikes.

San Juans

This incredibly large region includes some of the highest and most rugged hiking in the state. These hikes are much harder to get too but provide more solitude and more adventure than hiking in other parts of the state. This area is roughly the region south of I-70 and encompasses a huge area. Towns like Telluride, Silverton, and Durango will be nearby for hiking in this region.

The next section will now include some of the best hiking in Colorado. Hopefully, this provides a great introduction to some of the best places to hike in Colorado. The following hikes are in no particular order and will provide some background information on hike length, difficulty, and accessibility.
